UNIVERSAL JOINT.

Specification of Letters Patent.

Application filed February 13, 1918. Serial No. 216,919.

T 0 all to ham it may concern:

Be it known that l, HERBERT Coornn, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New Yorlr, have invented certain new and useful Improvements in Universal Joints, of which the following is a specification.

This invention relates to universal joints, and more particularly to that class of such device especially adapted for the efficient transmission of power, and has for its essential object the construction of a universal joint of the character set forth adapted to deliver power transmitted thereto in drillrection away from a straight line or in any driving angle with maximum efficiency and with minimum friction, wear or strain.

A further object of this invention is the provision of a universal joint embodying an improved construction especially adapted for the coupling together of the drive shaft and the propeller shaft of an automobile, the universal coupling means possessing culiar advantages of operation for the construction for which it is designed. to permit of movement in any driving angle to any desired amount.

With the foregoing and other objects in view as will from time to time hereinafter appear, this invention consists in the peculiar arrangement and combination of the various cooperating and reiated elements of a universal joint as further set forth in the following specification and more particularly pointed out in the appended claims.

Referring to the accompanying drawings forming a portion of this specification and illustrating the preferred embodiment of the invention, and in which the same reference characters are used to designate the same parts throughout,

Figure 1 is a perspective view of the joint with a portion of each shafting attached thereto;

Fig. 2 is a detail vertical section through. the joint;

Fig. 3 is a detail horizontal section through the joint;

Fig. 4: is a section on line 4, l of Fig. 2;

Fig. 5 is a section on line 5, 5 of Fig.

6 designates a cylindrical member hollowed out to receive a shaft 7 held in place therein by a tapered pin 8 driven through apertures suitably provided in the m mber 6 and the shaft 7, the member 6 being further provided with a reduced extension 9 terminatmg in an eye portion 10 flattened upon par allel sides and rounded to form the ball of a ball and socket universal joint as hereinafter described.

A second cylindrical member 11 is similarly hollowed out for the reception of a shaft 12, the member 11 having two parallel extensions 13, 141-, separated by parallel longitudinal slots 15, 16, the extensions 13, 14 being cut away interiorly at l7, 18, to form a socket for the ball member previously described.

In assembling the universal joint the eye 10 of the member 6 is inserted between the extensions through the slot 15 or 16 as the case may be, and then turned upon its axis, so that the eye 10 will aline with the slots 15, 16, and the ball portion of the eye 10 will engage the socket formed by the cut away portions 17, 18. While inthis position a member 19, comprising a hollow hank 20 and a head 21, flattened at the sides 22, 23 thereof to fit the slot 15, is inserted through the slot 15, the shank 2O entering the eye 10. r

A second member 24 somewhat similar to the member 19 and cooperating therewith is inserted through the opposite slot 16. A shank 25 thereof enters or telescopes with the hollow shank 20 of the member 19 in the center of the eye 10. Head 26 of the member 24 is within the slot 16 and is flattened at 27, 28, in order to fit the slot as shown in Fig. 5. H r

l/Vhen the assembled parts are in this position a suitable casing 29 provided with a curved lip 30 is slid into the position shown upon the member 11, the curved lip 30 engaging the heads 21 and 26 of the members 19, 2a, which are curved transversely at 81, 32, to fit the interior periphery of the lip 30. The casing 29 is held in place by spinning or pressing end 34!: into groove 85 suitably provided in member 11. The shaft 12 is held inplace by a taper pin 33 engaging suitable apertures bored for the purpose in the member 11 and the shaft 12.

By the construction above described any movement in one plane is provided for by the movement of the eye 10 within the socket formed by the cut away portions 17 and 18, wherein the eye 10 pivots vertically upon the shank 20 of the member 19, Which mem- Patented Feb. 15, 1921.

her is held from vertical movement by its location Within the slot 15, as is also the member 24 located in the slot 16.

Movement of the shafting in the other plane is provided for by the members 19 and 24 withintheir respective slots 1'5 and 16, the curved surfaces 81 and 32 of the said members formlng a ball and socket joint with the interior of the lip 30 of the casing 29.

By providing for the two out of line movements above described the device presents a universal joint permitting of a varied movement of the driven shaft carried thereby.

I realize that considerable variation of.

art will define the scope thereof.

WVhat I claim is:

1. In a universaljoint, a socket member having extensions at opposite sides, a ball member engaging said socketmember between said extensions, holding means carried by said ball member adapted to lie between the sides of said extensions to retain said ball member within sald socket, and means adapted to retain said ballretaining means in position.

2. In a universal joint, amember having extensions separated by slots and forming a socket, a. ball member adapted to engage said socket, the ball member being provided with anveye, a plurality of members adapted to engage'said eyeand saidslots to hold 1 said ball in. the socket, and means for re taming said members in said slots.

3. In a universal joint, a socket member having slots, a ball member adapted to engage the socket, members adapted to engage said ball member and said slots to permit horizontal and vertical movement of said ball and to prevent the rotation of the ball within the socket, and means for holding the ball retaining members in position.

4i. in a universal joint, a socket member having oppositely disposed slots, a ball member, and telescopic means carried by the ball member adapted to engage the slots in the socket member to permit horizontal and vertical angular movement of the ball within the socket but to prevent rotation therein.

5. In a universal joint, a member having extensions separated by slots and forming a socket, a ball member adapted to engage said socket, the ball member being provided with an eye, a plurality of members adapted to engage said eye and said slots to hold said ball in the socket, a tubular member adapted for retaining said members in said slots and means for attaching said tubular member to said socket member.

6. In a universal joint, a'socket member having slots, a ball member adapted to engage the socket, means adapted to engage said ball member and said slots to permit vertical and horizontal movement of said ball and to prevent the rotation of-the ball Within the socket, a tubular member adapted for holding the ball retainingmembers in position and means for holding said tubular member in position on said socket member.

7. In a universal joint, a socket member having extensionsseparatedbyslots, a ball member adapted to engage said socket mem her, a plurality of members to engage said zontal and vertical angular movement ofthe '80 ball member and said slots to permit horiball Within the socket but to prevent axial rotation therein, a tubular member adapted to hold sald members 1n said slots andmeans for holding tubular member 1n position.

In testimony whereofl atlix my signature in presence of two witnesses.
